Good for what? Intended use?

Using as major component of my media for container veggies

Looks like a high percentage of sapwood, but maybe not? You might want to post a picture in the Container Forum to get compliments on your medium.

Not very good for 5-1-1, sorry to say.

Forget the wet blankets, Teddy. The absolute best bagged soil amendment that's available in the KC area is a luscious blend of two composts (cotton burr and mushroom), pine bark fines, sphagnum peat moss, calcium and sulphur. We had some beds prepped by a landscaper who used straight cotton burr compost which wasn't fully composted and turned our new plantings yellow. The beds I prepped with "Max Mix" were spectacular from the get-go.

You don't want to apply the pine fines in too high a percentage, but they are wonderful as part of an amendment program.

The vast majority of potting media used by the commercial nursery trade is pine bark based...sometimes as the only ingredient. Pine BARK fines make an excellent potting medium.

The bagged potting mix I've used for a very long time is mostly pine bark, with a much smaller addition of sphagnum and perlite (and dolomitic lime to adjust pH) .

Looks like it would work out just fine....pardon the pun!
